ABSTRACT:
A method and apparatus for glitch protection for differential strobe input buffers in a source-synchronous environment. The present invention provides a solution to the problem of noise sensitivity of differential strobe input buffers in a source-synchronous environment, which may cause functional problems. The present invention enables the use of fully differential strobe signals to improve electrical performance of the source synchronous data transfers while removing the noise sensitivity problem associated with these signals. This is accomplished by providing a glitch protection circuit that provides protection against input glitches for a first predetermined period of time after each strobe transition. The present invention also provides a detection circuit that detects when both differential strobe signals are in the same logic state, which corresponds to a transition between bus masters (a dead cycle). The detection circuit causes the glitch protection circuit to latch the output signal of the glitch detection circuit.
